is it possible to fully overwrite the dimensioning text, i.e. not just add an inscription?
For drawings that are not to scale this function would be very useful. One could for instance underline the dimensions for identification.

For the German version it would also be good if the thousands separators were dots and the decimal mark were a comma.

Sometimes I use "Distance Tool" in a diagram not really to measure the size of an object, but just to indicate what is what, see attached example. In such a case it would be fine, if only the label will be displayed, not the measured value of distance.

You can customize the Arrow tool. Set Start and End Line Endings to Open Arrow and play with Leader Length, Leader Extension and Leader Offset (I have mine set to 0.375", 0.125" and 0.125" respectively). You will have to place text manually, which is not ideal, but gets you what you want. Search Help for Comment Styles Palette for info on tool customization.

Thank you Lev for your help. But using the Arrow Tool is not really the alternative solution for me. When I have to place the text manually, I'll still use the Distance Tool and place the text to cover the distance value by giving the text a white fill color. This works fine. The problem is, when I change or move the dimension line, I must manually adjust the text. So it would be fine, if a new feuture can be added so that only the label will be displayed, without the value of distance.
